All the interfaces are DOWN


#1

Hello,

I’m whole new in VyOS. As I’ve understood the whole configuration of the vyos had to be done using the “configuration” mode.

I’ve done a few tests but all my interfaces are considered as state Up and link Down !

pb_down|690x292

I’ve create two VYos 1.8 on the same adressing plan to make some tests and I think I’ve missed a step. I’ve rechecked the MAC addresses, and they look OK. Is there a reason why my interfaces are still considered as down ?

Thank you for your answer.


#2

can you share your config? Did you assign IP addresses or DHCP to the interfaces?


#3

I’ve difficulties to export the whole configuration considering all my interfaces are dead for the moment. But I’ve added four interfaces on VyOS all configured the same way :

set interfaces ethernet eth0 address ‘192.168.0.19/27’
set interfaces ethernet eth0 duplex ‘auto’
set interfaces ethernet eth0 ipv6 ‘disable-forwarding’
set interfaces ethernet eth0 ipv6 dup-addr-detect-transmits ‘1’
set interfaces ethernet eth0 smp-affinity ‘auto’
set interfaces ethernet eth0 speed ‘auto’
set interfaces ethernet eth0 description ‘Admin’
set interfaces ethernet eth1 duplex ‘auto’
set interfaces ethernet eth1 address ‘192.168.10.25/27’
set interfaces ethernet eth1 ipv6 ‘disable-forwarding’
set interfaces ethernet eth1 ipv6 dup-addr-detect-transmits ‘1’
set interfaces ethernet eth1 smp-affinity ‘auto’
set interfaces ethernet eth1 speed ‘auto’

set interfaces ethernet eth3 address ‘192.168.20.19/28’

and added a virtual IP

set interfaces ethernet eth3 vrrp vrrp-group 3 virtual-address ‘192.168.20.110/28’
set interfaces ethernet eth3 vrrp vrrp-group 3 advertise-interval ‘1’
set interfaces ethernet eth3 vrrp vrrp-group 3 preempt ‘true’
set interfaces ethernet eth3 vrrp vrrp-group 3 priority ‘100’
set interfaces ethernet eth3 vrrp vrrp-group 3 ‘rfc3768-compatibility’

You can use serial console even if network is completely down.

The config looks right, so I suppose the issue is elsewhere. What is it running on? Physical hardware or a VM? What does “run show interfaces ethernet ethX physical” show?


#5

It’s a VMWare 6.5 VM

Here is the result of your command for eth0

Ok, I’ve found a solution when I saw that duplex and speed were unknown.

I have a generic Linux 64 bits as VM, so when I added the network interfaces in the VM they were declared with a type “E1000”. However VyOS doesn’t seems to support E1000.

Solution :

  • Delete the network interfaces if they are in E1000
  • Recreate them in VMXNet 3.

Now the interfaces are seen as UP.

Thank you very much.
